Karma.

God gave us the gift of free will, it is up to us what we do with it.
The question of free will is whether rational agents exercise control over their actions and decisions. Lately I've been so bored with life that I've manipulated things that weren't any of my business. Hurting people for my own sick amusement. Well karma finally bit me in the ass, and I learned from it. The effects of all deeds are viewed as actively shaping past, present, and future experiences. You have to think of the outcome of what you're doing, the cause and effect. I wish I did that before.
